How to Make the Boldest, Brightest Tie-Dye!

Science Fair Project Idea

Scientific Method

The clothes you wear are made of fibers that come from many different sources. Some fabrics are made from natural fibers, and some from manufactured or totally synthetic fibers. In this science fair project, you will explore how different fiber types react with dye. Are you dye-ing to find out which works best? Read more

There are many occasions to light candles. When you did, have you ever looked closely at the flame? Which part of the candle is actually burning? Can you tell? Is it the wick, the solid wax, the liquid wax or something else? In this activity you will light some candles to find out—no special occasion required! Read more

Race Your Marbles to Discover a Liquid's Viscosity

Science Fair Project Idea

Scientific Method

How do you like your mashed potatoes? Thin and whipped smooth? Or thick and mashed into chunks? Your mouth checks out not just the taste of your food, but its viscosity, or how it flows on your tongue, every time you take a bite! In this science fair project, you'll learn what viscosity is, and how to measure it in common liquids around your home. Read more

The Chemistry of Hair Highlights

Science Fair Project Idea

Scientific Method

Have you ever tried to make parts of your hair lighter than the rest of your hair? Perhaps the way you tried to do it did not lighten it or maybe it turned out a weird orange color? With this science project you can understand why. Read more

Teach your students how to make plastic out of milk in this hands-on lesson plan! You will conduct a simple milk-transforming experiment to explore how plastics can be derived from a natural resource such as milk. Students will perform their own experiments and can even create a product from their resulting organic casein polymer. Read more

NGSS Performance Expectations:

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-3. Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.

Use a Calorimeter to Measure the Heat Capacity of Water

Science Fair Project Idea

Scientific Method

Along with its many other interesting properties, water has the ability to absorb a lot of heat energy, while only experiencing a relatively small change in temperature. One way this property affects us directly is that our bodies don't change temperature rapidly on hot or cold days, since we are made up of mostly water. In this chemistry-with-an-electronics-flair science fair project, you will determine how the temperature of a small volume of water changes as you add precise amounts of heat… Read more

Where does CO₂ come from and how does excess carbon dioxide in the atmosphere affect the ocean and aquatic life? In this lesson students are introduced to the carbon cycle and explore pH and acidification with hands-on experiments. They then connect their experimental data with real-world data to evaluate claims about carbon dioxide and ocean acidification. Finally, students are introduced to how different companies and research groups are using green chemistry to build carbon capture… Read more

Which Type of Water is the Hardest?

Science Fair Project Idea

Scientific Method

Do you want your hair to be shiny after you wash it? Do you want your clothes to stay bright and soft after laundering, and last a long time? You might think that a special shampoo or detergent can make this happen, but in this chemistry science fair project, you'll discover that how well people and things get clean has a lot more to do with the type of water used for washing than any special shampoo or soap. Did you know that water can be classified as either soft or hard? Soft water lathers… Read more

These lessons use open-ended exploration to introduce students to biopolymers and the chemistry behind cross-linking. Students will draw inspiration from biology and use authentic scientific practices to design and create colorful string creations from a natural polymer, alginate. Learning Objectives Students will: Engage in authentic science practices through open-ended exploration. Create a string using polymers harvested from living algae. Manipulate the properties of a… Read more

Does Wet Hair Float or Cling?

STEM Activity

Have you ever noticed how hair moves freely when it is under the water, but clings together as soon as it emerges out of the water? Not only human hair does this; when wet dogs shake themselves after a swim, their hair clings together in strands. Try this activity to see why wet hair is far less fluffy than dry hair! Read more
